With what effrontery then will the Papists boast that they possess the gospel, which is not only corrupted by many inventions, but more than adulterated by many wicked doctrines? Let us remember that it is not enough to retain the name of the gospel, and some kind of summary of its doctrines, if its solid purity do not remain untouched. Where are the men who, by pretended moderation, endeavor to bring about a reconciliation between us and the Papists? as if the doctrine of religion, like a matter affecting money or property, could be compromised. With what abhorrence would such a transaction have been regarded by Paul, who affirms that it is not the true gospel, if it is not pure! (Commentary on Galatians 2:5)
Gracious, that sounds downright….schismatic! Well, at least to those who have missed the rather painfully obvious fact that without the gospel, unity is a myth.
